项目摘要
Within this project we will carry out theoretical and experimental studies of novel types of compact THz sources where semiconductor laser diodes will be combined with a novel dipole/spiral and waveguide photoconductor devices. Specifically, we propose to design, fabricate and assess the performance of the material systems of amorphous/nanocrystalline silicon and quantum-dot semiconductors as materials having short electron-hole photocarrier lifetimes and high photosensitivity at 780-1300nm. In addition to fully characterising and optimising the dual- and multi-longitudinal modes diode lasers we will evaluate the performance of these lasers in the optical pumping of the dipole/spiral and waveguided antennae for obtaining THz power levels in the >100 microwatts range with optimised beam characteristics. The overall objective of this work is to produce a diode-laser-driven, ultra-compact THz source having some potential for additional functionality through its frequency tunability.
在这个项目中,我们将进行新型紧凑型太赫兹源的理论和实验研究,其中半导体激光二极管将与新型偶极/螺旋和波导光电导体器件相结合。具体而言,我们建议设计,制造和评估的材料系统的非晶/纳米晶硅和量子点半导体的材料具有短的电子-空穴光生载流子寿命和在780- 1300 nm的高光敏性的性能。除了充分表征和优化双纵模和多纵模二极管激光器外,我们还将评估这些激光器在偶极/螺旋和波导天线的光泵浦中的性能,以获得>100微瓦范围内的THz功率水平,并优化光束特性。这项工作的总体目标是产生一个二极管激光驱动的,超紧凑的太赫兹源,通过其频率可调谐性具有一些潜在的额外功能。
